With the Boners cockring, you'll enjoy a harder and longer-lasting erection and heightened sensations during orgasm. Place the ring around the base of the penis when it's flaccid, and adjust the ring to the desired size by sliding the adjuster up or down. During an erection, the ring will snugly fit around the penis, reducing blood flow. Thanks to the broad top section, both you and your partner can enjoy delightful vibrations together! Hold the button for 3 seconds until the LED light starts to illuminate. Press the button to start the vibrations and switch between modes. Which one will become your favorite?Clean the cockring after use with lukewarm water and a toy cleaner, and easily recharge the cockring with the included USB cable.
